Even if I lose all of my property, I can rely on the welfare state to provide for my needs so I will not have a valid reason to steal from you.
That's like saying "I don't have to steal from you, I can just ask someone else to do it for me and then receive the stolen property". That's called aiding and abetting.
There are plenty of other alternatives. The one I favour is respecting each others opinions while disagreeing. My morality will prevent me from initiating violence anyway and even in the case of self defence, I will look for alternatives (such as running away).
Right, so you refuse to do your own dirty work but you have no problem advocating thugs in blue costumes doing it for you.
